INDEMNIFICATION AND CONTRIBUTION. (a) (i) The Company, Converium Holding and Converium AG, jointly and severally, agree to indemnify and hold harmless each Underwriter, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Securities and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a "CONTROL PERSON"), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses as reasonably incurred in connection with defending or investigating any such action or claim) arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any Preliminary Prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or arising out of any omission or alleged omission to state therein, in the light of the circumstances in which they were made, a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities arise out of any such untrue statement or omission or alleged untrue statement or omission based upon Underwriter Information. (ii) The indemnity with respect to any Preliminary Prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), described in Section 7(a) shall not inure to the benefit of any Underwriter from whom the person asserting such losses, claims, damages or liabilities purchased Securities, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Securities by the Company to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities. (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, Converium Holding and Converium AG, and each person, if any, who controls the Company Converium Holding and Converium AG within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company, Converium Holding and Converium AG to such Underwriter, but only with reference 21 to information in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendments or supplements thereto based upon Underwriter Information and only to the extent that such information is untrue or omits material information. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to paragraphs 7(a) or 7(b) of this Section 7, such person (the "INDEMNIFIED PARTY") shall promptly notify the person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing, but the failure to notify the indemnifying party shall not relieve it from liability which it may have to any indemnified party; the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for (a) all Underwriters, affiliates and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and (b) the Company, Converium Holding or Converium AG, their directors, their officers who sign the Registration Statement and each person, if any, who controls the Company, Converium Holding or Converium AG within the meaning of either such Section. All such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters, affiliates and any controlling persons of any Underwriters, such firm shall be jointly designated in writing by the Representatives. In the case of any such separate firm for Converium Holding, Converium AG and the Company, and any directors, officers and controlling persons of the Company, Converium Holding or Converium AG, such firm shall be designated in writing by Converium Holding, Converium AG and the 22 Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) To the extent the indemnification provided for in paragraphs 7(a) and 7(b) of this Section 7 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by Converium Holding, Converium AG and the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of Converium Holding, Converium AG and the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by Converium Holding, Converium AG and the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by Converium Holding, Converium AG and the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of Converium Holding, Converium AG and the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact 23 relates to information supplied by Converium Holding, Converium AG or the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. (e) Converium Holding, Converium AG, the Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph 7(d) of this Section 7. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, Converium Holding and Converium AG, each officer of the Company, Converium Holding and Converium AG who signed the Registration Statement, and each person, if any, who controls the Company, Converium Holding or Converium AG within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company, Converium Holding or Converium AG. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Firm Securities set forth opposite their respective names in Schedule A hereto and not joint. (f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of 24 Converium Holding, Converium AG and the Company contained in this Underwriting Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Underwriting Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, or Converium Holding, Converium AG or the Company, their respective officers or directors or any person controlling Converium Holding, Converium AG and the Company and (iii) acceptance of and payment for any of the Securities. 8. TERMINATION OF UNDERWRITING AGREEMENT. (a) Termination. This Underwriting Agreement shall be subject to termination by notice given by the Representatives to the Company, if (a) after the execution and delivery of this Underwriting Agreement and prior to the Closing Time (i) there has been any material adverse change or any developments likely to result in a material adverse change in the condition financial or otherwise, or in the earnings or business affairs of Converium Holding, Converium AG or the Company and their subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, (ii) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the SWX Swiss Exchange, the New York Stock Exchange or the National Association of Securities Dealers, Inc., (iii) trading of any securities of Converium Holding, Converium AG or the Company shall have been suspended on any exchange or in any over-the-counter market, (iv) a general moratorium on commercial banking activities in Switzerland, Luxembourg or New York shall have been declared by Swiss, Luxembourg or United States Federal or New York State authorities, respectively, or (v) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions that, in the judgment of the Representatives is material and adverse, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, Luxembourg or Switzerland and (b) in the case of any of the events specified in clauses 8(a)(i) through 8(a)(v), such event, singly or together with any other such event, makes it, in the judgment of the Representatives, impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus. 9. DEFAULT BY ONE OR MORE OF THE UNDERWRITERS. This Underwriting Agreement shall become effective upon the execution and delivery hereof by the parties hereto. 25 If, on the Closing Time or a Date of Delivery, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Securities to be purchased on such date, the non-defaulting Underwriters shall be obligated severally in the proportions that the number of Firm Securities set forth opposite their respective names in Schedule A hereof bears to the aggregate number of Firm Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Securities that any Underwriter has agreed to purchase pursuant to this Underwriting Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such number of Securities without the written consent of such Underwriter. If, on the Closing Time, any Underwriter or Underwriters shall fail or refuse to purchase any Firm Securities and the aggregate number of Firm Securities with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Securities to be purchased, and arrangements satisfactory to the Representatives, Converium Holding, Converium AG and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Underwriting Agreement shall terminate without liability on the part of any non-defaulting Underwriter, Converium Holding, Converium AG or the Company. In any such case, either the Representatives, Converium Holding, Converium AG and the Company shall have the right to postpone the Closing Time, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. If, on a Date of Deliver, any Underwriter or Underwriters shall fail or refuse to purchase any Additional Securities and the aggregate number of Additional Securities with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Securities to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Securities or (ii) purchase not less than the number of Additional Securities that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Underwriting Agreement. If this Underwriting Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of Converium Holding, Converium AG or the Company to comply with the terms or to fulfill any of the conditions of this Underwriting Agreement, or if for any reason Converium Holding, Converium AG or the Company shall be unable to perform 26 its obligations under this Underwriting Agreement, Converium Holding, Converium AG and the Company, jointly and severally, agree to reimburse the Underwriters or such Underwriters as have so terminated this Underwriting Agreement with respect to themselves, for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Underwriting Agreement or the offering contemplated hereunder. It is understood and agreed that the Representatives and the Underwriters shall not be entitled to any out-of-pocket expenses if this Agreement is terminated pursuant to the second paragraph of this Section 9. 10. NOTICES. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.
